Referring to FIG. 1 , the present disclosure provides an aerosol generating device, the aerosol generating device includes an atomizer 100 and a battery device. When the atomizer 100 is electrically connected to the battery device, under the electric driving of the battery device, the aerosol-forming substrate is heated and atomized by the atomizer 100 to form smoke.

It should be noted that “axial” refers to the connection direction of the atomizer 100 and the battery device, “radial” refers to the direction perpendicular to the “axial”. “Lower end” refers to the end of each portion, component of the atomizer 100 that is close to the battery device in the axial direction of the atomizer 100, “upper end” refers to the end of each portion, component of the atomizer 100 that is away from the battery device in the axial direction of the atomizer 100. “Upper end face” means the flat and/or curved surface of the upper end, “lower end face” refers to the flat and/or curved surface of the lower end.

Referring to FIGS. 1-3 , the atomizer 100 includes a liquid storage assembly 10, an atomizing assembly 20, a base assembly 30 and a mouthpiece assembly 40. The atomizing assembly 20 is arranged on the base assembly 30, the base assembly 30 is installed at one end of the liquid storage assembly 10, and the mouthpiece assembly 40 is installed at the opposite end of the liquid storage assembly 10 relative to the base assembly 30. In use, the liquid storage assembly 10 supplies the aerosol-forming substrate to the atomizing assembly 20, the atomizing assembly 20 heats the aerosol-forming substrate under the electric driving of the battery device, the aerosol-forming substrate is heated to generate smoke, the smoke flows out through the mouthpiece assembly 40, and the user can inhale the atomized smoke through the mouthpiece assembly 40.

The base assembly 30 is detachably connected to one end of the liquid storage assembly 10. The atomizing assembly 20 is arranged between the base assembly 30 and the liquid storage assembly 10. The liquid storage assembly 10 includes an elastic member 14, the elastic member 14 is elastically biased between the liquid storage assembly 10 and the atomizing assembly 20. When the base assembly 30 is detached from the liquid storage assembly 10, the atomizing assembly 20 is ejected out by the elastic member 14.

In this embodiment, the liquid storage assembly 10 includes a housing 11 in which a liquid storage chamber 111 is provided, a connecting body 12 provided in the housing 11, a liquid sealing member 13 slidably received in the connecting body 12, and an elastic member 14 axially telescopically provided between the connecting body 12 and the liquid sealing member 13. The atomizing assembly 20 is movably installed in the connecting body 12. An atomizing chamber 231 is provided in the atomizing assembly 20. The base assembly 30 is detachably connected to the connecting body 12. The liquid sealing member 13 and the elastic member 14 are arranged in sequence along the loading direction of the atomizing assembly 20. The liquid sealing member 13 can be switched between a liquid discharging position and a liquid sealing position. During the course of connecting the base assembly 30 to the liquid storage assembly 10, the liquid sealing member 13 moves and compresses the elastic member 14 under the pushing of the atomizing assembly 20, the liquid sealing member 13 is located in the liquid discharging position, and the aerosol-forming substrate in the liquid storage chamber 111 can flow into the atomizing chamber 231. During the course of separating the base assembly 30 from the liquid storage assembly 10, the liquid sealing member 13 is pushed to the liquid sealing position under the elastic restoring force of the elastic member 14, the liquid sealing member 13 blocks the aerosol-forming substrate in the liquid storage chamber 111 from flowing into the atomizing chamber 231, and the atomizing assembly 20 is ejected to the outside by the elastic member 14. The gap between the housing 11 and the connecting body 12 forms the liquid storage chamber 111.

Specifically, the connection or separation of the base assembly 30 and the liquid storage assembly 10 means that the base assembly 30 can be connected to or separated from the connecting body 12 and/or the housing 11. The manner in which the base assembly 30 is connected to the connecting body 12 and/or the housing 11 includes, but is not limited to, a detachable connection manner such as snapping connection, plugging connection, or screwing connection, etc., as long as when the liquid sealing member 13 is located in the liquid discharging position, the atomizing assembly 20 is fixed. In this embodiment, the base assembly 30 is connected to the connecting body 12 by means of screwing connection.

Specifically, the elastic member 14 is a spring. It is understood that, in another embodiment, the elastic member 14 may also be an element with elasticity such as a stainless steel elastic sheet or silicone.

It can be understood that, in another embodiment not shown, the atomizing assembly 20 is detachably connected to the liquid storage assembly 10, so as to enable the liquid sealing member 13 to switch between the liquid discharging position and the liquid sealing position. When the atomizing assembly 20 is detached from the liquid storage assembly 10, the atomizing assembly 20 is ejected out by the elastic member 14.

In summary, when the user needs to use the atomizer 100, during the course of connecting the base assembly 30 to the liquid storage assembly 10, the liquid sealing member 13 moves and compresses the elastic member 14 under the pushing of the atomizing assembly 20, when the liquid sealing member 13 is located in the liquid discharging position, the aerosol-forming substrate in the liquid storage chamber 111 can flow into the atomizing chamber 231. After the use of the atomizer 100 by the user, during the course of separating the base assembly 30 from the liquid storage assembly 10, the liquid sealing member 13 is pushed to the liquid sealing position under the elastic restoring force of the elastic member 14, the liquid sealing member 13 blocks the aerosol-forming substrate in the liquid storage chamber 111 from flowing into the atomizing chamber 231. Therefore, when the user needs to clean the dirt in the atomizing chamber 231 or replace the atomizing assembly 20, the base assembly 30 can be separated from the liquid storage assembly 10, the elastic member 14 can eject the atomizing assembly 20 to the outside, which is convenient for the user to take out the atomizing assembly 20.

When the liquid sealing member 13 is located in the liquid discharging position, the liquid inlet hole 121 is opened, and the liquid inlet opening 22 communicates with the atomizing chamber 231 and the liquid inlet hole 121. When the liquid sealing member 13 is located in the liquid sealing position, the liquid inlet hole 121 is shielded by the liquid sealing member 13. It can be understood that, in another embodiment not shown, the liquid inlet hole 121 is formed by the gap between the connecting body 12 and the lower end of the liquid storage assembly 10.

In one embodiment, the housing 11 is made of a transparent material such as glass.

It can be understood that, in another embodiment, the connecting sleeve 123 may also be detachably connected to the upper cover 122 by means of snapping connection or plugging connection. The upper end of the elastic member 14 elastically abuts against the inner top wall of the connecting sleeve 123, and the lower end of the elastic member 14 elastically abuts against the upper end of the liquid sealing member 13. When the elastic member 14 is in the natural state, the liquid sealing member 13 closes the liquid inlet hole 121, and at this time, the liquid sealing member 13 is in the liquid sealing position, and in this position, the aerosol-forming substrate cannot flow into the connecting sleeve 123 through the liquid inlet hole 121.

In one embodiment, the upper cover 122 and the housing 11 are two independent elements, and the two are detachably connected by means of snapping connection or plugging connection.

The main body 1231 is provided with the liquid inlet hole 121, the liquid inlet hole 121 communicates with the liquid storage chamber 111 and the inner cavity of the main body 1231. Therefore, when the atomizer 100 is not in use, the aerosol-forming substrate in the liquid storage chamber 111 can contact the side wall of the liquid sealing member 13 through the liquid inlet hole 121. It can be understood that, in another embodiment, the main body 1231 can be omitted, in this case, the aerosol-forming substrate in the liquid storage chamber 111 can directly contact the liquid sealing member 13.

In one embodiment, the connecting member 37 is connected to the connecting portion 1232 through threads, so that the atomizing assembly 20 and the liquid storage assembly 10 are fixedly connected. It can be understood that, in another embodiment, the connecting member 37 may also be detachably connected to the connecting portion 1232 by means of snapping connection or plugging connection, as long as the connecting member 37 slides axially upward relative to the connecting sleeve 123 in place, the connecting member 37 and the connecting sleeve 123 are fixedly connected, so as to fix the atomizing assembly 20 on the liquid storage assembly 10.

In one embodiment, a fourth abutting member 38 is sleeved on the connecting member 37. When the connecting member 37 and the connecting portion 1232 are connected in place, the fourth abutting member 38 can prevent the connecting member 37 from being in rigid contact with the housing 11 to cause the both to wear. Specifically, the fourth abutting member 38 is made of a material with good sealing properties such as silicone or rubber.

In one embodiment, the connecting member 37 is provided with a mounting hole 371 for accommodating the atomizer assembly 20, and the mounting hole 371 communicates with the inner cavity of the base 31. The atomizing assembly 20 can extend into the inner cavity of the base 31 from the mounting hole 371, and the atomizing assembly 20 is electrically connected with the base 31 and the electrode contact member 35.

The atomizing assembly 20 includes an atomizing casing 23 and a heating structure disposed in the atomizing casing 23. The inner cavity of the atomizing casing 23 is the atomizing chamber 231 which communicates with the vent hole 1221. The atomizing casing 23 is provided with the liquid inlet opening 22 communicating with the atomizing chamber 231. The heating structure includes a liquid absorbing member and a heating member in contact with each other. The liquid absorbing member and the heating member are both received in the atomizing chamber 231. The liquid absorbing member has the ability to absorb the aerosol-forming substrate.

The liquid absorbing member can be made of cotton, cotton cloth, fiber rope and other materials that are easy to absorb liquid. The heating member can be made of stainless steel, nickel-chromium alloy, ceramics and other materials.

The atomizing chamber 231 is communicated with the air inlet opening 311, and the external air can flow into the atomizing chamber 231 through the air inlet hole 321 and the air inlet opening 311 in sequence.

In summary, since the connecting member 37 is connected with the connecting portion 1232 through threads, when the user needs to use the aerosol generating device, the connecting member 37 can move upward along the axial direction of the connecting sleeve 123 by rotating the base assembly 30. When the atomizing assembly 20 extends into the connecting sleeve 123 and abuts against the liquid sealing member 13, the liquid sealing member 13 is driven to move upward under the pushing of the atomizing assembly 20, thereby compressing the elastic member 14, and the liquid inlet hole 121 is opened, the aerosol-forming substrate in the liquid storage chamber 111 enters into the atomizing chamber 231 through the liquid inlet hole 121 and the liquid inlet opening 22 in sequence and is absorbed by the liquid absorbing member, the heating member heats and atomizes the aerosol-forming substrate absorbed by the liquid absorbing member, the aerosol-forming substrate generates smoke under the heating action of the heating member, and the smoke fills up the atomizing chamber 231. At this time, the liquid sealing member 13 is located in the liquid discharging position. In this position, the external air can enter the atomizing chamber 231 through the air inlet hole 321 and the air inlet opening 311 in sequence and mix with the atomized smoke, the smoke after being mixed with the air flows out from the vent hole 1221. After the suction, the base assembly 30 can be reversely rotated to cause the connecting member 37 to move downward along the axial direction of the connecting sleeve 123, the liquid sealing member 13 can be reset under the elastic force of the elastic member 14, thereby closing the liquid inlet hole 121 again, the liquid sealing member 13 returns to the liquid sealing position again, the aerosol-forming substrate cannot flow out. At this time, the connecting member 37 is still connected with the connecting sleeve 123 through the threads, as long as the liquid sealing member 13 can be reset under the action of the elastic force of the elastic member 14 to close the liquid inlet hole 121 again. When the user needs to separate the atomizing assembly 20 from the atomizer 100 and take out the atomizing assembly 20, the base assembly 30 is continued to be reversely rotated, so that the connecting member 37 is continued to rotate downward along the axial direction of the connecting sleeve 123 until the base assembly 30 is separated from the liquid storage assembly 10.

In one embodiment, the liquid storage assembly 10 further includes a fifth abutting member 16 sandwiched between the liquid sealing member 13 and the connecting sleeve 123.

A mounting portion 412 is formed around the inner wall of the smoking opening 411 and protrudes downward along the axial direction of the smoking opening 411. The space enclosed by the inner peripheral wall of the mounting portion 412 is a cavity for mounting the mouthpiece seat 42, and the mouthpiece seat 42 is installed in the cavity.

In one embodiment, the mouthpiece seat 42 includes seat bodies 421 disposed in the two sliding grooves, and a cylinder 422 disposed at the upper end of the seat body 421. The seat bodies 421 are slidably engaged in the two sliding grooves, the cylinder 422 is sleeved on the mounting portion 412, and the inner cavity of the cylinder 422 communicates with the smoking opening 411 and the vent hole 1221. It can be understood that the liquid injection cover 41 can slide radially relative to the upper cover 122. In addition, the liquid injection cover 41 can also slide axially relative to the upper cover 122.

The fixing member 43 is engaged with the mouthpiece seat 42. In one embodiment, the fixing member 43 and the cylinder 422 are detachably connected, the detachable connection method includes but is not limited to snapping connection, plugging connection, and the like. It can be understood that, in another embodiment, the fixing member 43 may also be integrally formed with the mouthpiece seat 42.

The limiting member 44 is engaged with the liquid injection cover 41. In one embodiment, the limiting member 44 and the liquid injection cover 41 are two independent components, the two are detachably connected by means of snapping connection or screw connection. The upper end face of the limiting member 44 can abut against the inner surface of the liquid injection cover 41. Specifically, when the liquid injection cover 41 slides axially downward relative to the mouthpiece seat 42, the liquid injection cover 41 can drive the limiting member 44 to slide axially downward relative to the mouthpiece seat 42. It can be understood that, in another embodiment not shown, the limiting member 44 may also be integrally formed with the liquid injection cover 41.

One end of the restoring member 45 is connected to the fixing member 43, and the other end of the restoring member 45 is connected to the limiting member 44. In one embodiment, the restoring member 45 is a spring. It is understood that, in another embodiment, the restoring member 45 may also be an elastic element such as a spring sheet.

The mouthpiece 46 is inserted into the mounting portion 412, the mouthpiece 46 is provided with a smoking hole 461 that communicates with the outside environment and the smoking opening 411.

The side wall of the upper cover 122 is the assembling surface 47 for assembling with the mouthpiece assembly 40. When the mouthpiece assembly 40 and the upper cover 122 are assembled, the seat bodies 421 are engaged in the two sliding grooves, the lower end face of the mouthpiece seat 42 is in contact with the upper end face of the upper cover 122, the inner wall of the liquid injection cover 41 abuts against the assembling surface 47. At this time, the liquid injection cover 41 cannot slide radially relative to the upper cover 122, the restoring member 45 is in a compressed state, and the mouthpiece assembly 40 and the liquid storage assembly 10 are fixed. By providing the restoring member 45, when the mouthpiece assembly 40 is assembled in place, the vibration between the mouthpiece assembly 40 and the liquid storage assembly 10 can be reduced, so as to make the connection more stable.

In summary, when it is necessary to move the mouthpiece assembly 40 relative to the liquid storage assembly 10 and inject liquid into the liquid storage chamber 111 through the liquid injection hole 1222, the inner wall of the liquid injection cover 41 can be separated from the assembling surface 47 by pulling the liquid injection cover 41 upward along the axial direction of the upper cover 122. During the upward sliding process of the liquid injection cover 41, the liquid injection cover 41 drives the limiting member 44 to slide axially upward relative to the mouthpiece seat 42. At this time, during the upward movement of the limiting member 44, the restoring member 45 is further compressed. When the lower end face of the liquid injection cover 41 is located at the same level with the upper end face of the upper cover 122 or above the upper end face of the upper cover 122, at this time, the liquid injection cover 41 can be pushed along the radial direction of the upper cover 122, and the liquid injection cover 41 drives the seat bodies 421 to slide in the two sliding grooves. When the seat bodies 421 move a certain distance along the extending direction of the sliding grooves, the liquid injection hole 1222 is exposed. By setting the restoring member 45, when the liquid injection is completed and the mouthpiece seat 42 is pushed back to the original position, the limiting member 44 is automatically pushed downward due to the elastic restoring force of the restoring member 45, the limiting member 44 drives the liquid injection cover 41 to move downward, to finally make the inner wall of the liquid injection cover 41 abut against the assembling surface 47 of the upper cover 122 and prevent radial movement of the liquid injection cover 41. At this time, the mouthpiece assembly 40 is locked again and cannot be filled with liquid. The atomizer 100 of the present disclosure increases the assembly difficulty of the liquid storage assembly 10 and the mouthpiece assembly 40, making it difficult to assemble and disassemble the two, thereby avoiding the leakage of the aerosol-forming substrate stored in the liquid storage chamber 111 or even the occurrence of accidental ingestion of the aerosol-forming substrate.

The battery device is connected to the connecting end 312, so that the positive electrode and the negative electrode on the battery device are electrically connected to the electrode contact member 35 and the base 31, respectively. Thus, the atomizer 100 can heat the aerosol-forming substrate under the electric driving of the battery device and atomize the aerosol-forming substrate into smoke for the user to inhale.

The beneficial effects of the present disclosure are: in the atomizer 100 and the aerosol generating device using the atomizer 100 provided by the present disclosure, the atomizing assembly 20 is arranged between the base assembly 30 and the liquid storage assembly 10, the elastic member 14 is elastically biased between the liquid storage assembly 10 and the atomizing assembly 20. When the base assembly 30 is detached from the liquid storage assembly 10, the atomizing assembly 20 is ejected out by the elastic member 14, so as to facilitate the user to take out the atomizing assembly 20.
